Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The pitch control system is easy to implement, but the response is slow and output power variation is large. The aerodynamic power control for the variable speed wind turbine can limit the power into the turbine by reducing the angle of the blades. The pitch control has a large response time. Therefore, fast torque changes caused by wind gusts will affect the generator. The speed range of the generator is depending on the converter voltage and the load situation. A higher voltage available for the converter in the rotor circuit, will give a higher range of speed. A speed was chosen to make the generator choose the mechanical speed, which gives the best power output related to the wind speed. A rate limiter was chosen to avoid fast changes in the mechanical speed. The scaling of the converter could be investigated and compared with the winding ratio of the machine, to find the optimal winding ratio compared with bus voltage in the converter. The response time is mainly dictated by the hydraulic actuator, which limits the performance of the system. The controller should be used in conjunction with the pitch control system to avoid large losses during steady state operation. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Today production of electricity in the world is mainly fossil fuel based. Eco-friendly power generation is a burning issue for power generation. Solar Energy solves this problem very well. Scientists are trying to increase the efficiency of Solar PV modules to use them more efficiently as an alternate source of fossil fuel for power generation. But efficiency of Solar PV Cells and Modules can reduce due to faults generated inside of them. This paper tries to analyze and calculate the reduction of efficiency for faults associated with Solar PV cell and modules. Besides, different fault detection procedures are also discussed that are adopted worldwide. Previous studies have concerned homogeneous systems with a large set of parameters being observed, while this study is focused on a more restrictive case. The first problem is to discover immediate faults occurring in solar panels. A new online algorithm is developed in MATLAB/SIMULINK based on similarity measures within a single installation. It performs reliably and is able to detect all significant faults over a certain threshold. The second problem concerns measuring degradation over time. 72 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An electrical network is an interconnection of electrical components (e.g. batteries, resistors, inductors, capacitors, switches) or a model of such an interconnection of consisting of electrical elements (e.g. voltage sources, current sources, resistances, inductances, capacitances). It is a network consisting of a closed loop, giving a return path for the current. They are thus more easily analyzed and experimentally determined. This book provides an overview of the basics of electrical and electronic engineering that are required at the undergraduate level. Efforts have been taken to keep the complexity level of the subject to bare minimum so that the students of non electrical/electronic can easily understand the basics. So far this book has examined topologies and networking standard. All the experiments in network device laboratory are explained in details with standard examples. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Hoy en día, la producción de electricidad en el mundo se basa principalmente en combustibles fósiles. La generación de electricidad respetuosa con el medio ambiente es una cuestión candente. La energía solar resuelve muy bien este problema. Los científicos están tratando de aumentar la eficiencia de los módulos fotovoltaicos solares para utilizarlos de manera más eficiente como una fuente alternativa de combustible fósil para la generación de energía. Pero la eficiencia de las células y módulos solares fotovoltaicos puede reducirse debido a los fallos que se generan en su interior. Este trabajo trata de analizar y calcular la reducción de la eficiencia por fallos asociados a las células y módulos solares fotovoltaicos. Además, se discuten diferentes procedimientos de detección de fallos adoptados en todo el mundo. Los estudios anteriores se han referido a sistemas homogéneos con un amplio conjunto de parámetros observados, mientras que este estudio se centra en un caso más restrictivo. El primer problema consiste en descubrir los fallos inmediatos que se producen en los paneles solares. Se desarrolla un nuevo algoritmo en línea en MATLAB/SIMULINK basado en medidas de similitud dentro de una misma instalación. Su funcionamiento es fiable y es capaz de detectar todos los fallos significativos por encima de un determinado umbral. El segundo problema se refiere a la medición de la degradación a lo largo del tiempo. 68 pp. Spanisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The new generation of FACTS controllers is based on Voltage Source Converter (VSC) using self-commutating devices like GTO and IGBTs. The application of these controllers brings up new challenges, not only in hardware implementation, but also in design of controllers. On-going deregulation exercise in the electric power industry has inspired considerable research interest in the area of improvement of the power factor in power systems. The book reports an investigation on effects of small signal model control scheme on improvement of the power factor in power systems, using a STATic synchronous COMpensator (STATCOM). The control scheme is simulated and all implementing peripherals are designed. The book contains five chapters. Chapter 1 gives briefly description of STATCOM and its modeling has been described in Chapter 2. Chapter 3 brings the details of control strategy small signal methods and its simulations in MATLAB/SIMULINK platform and implementing hardware design is described in Chapter 4. In Chapter 5, the principle and design of an artificial transmission line for 576 miles is given. 120 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Power electronics blends the main area of Electrical engineering, power electronics and control. As a result of technological evaluation many more semiconductor devices and their combinations are available. Flexible AC Systems (FACTS) is a controller and it is a technology pioneered by N.G.Hingorani and L.Gyugyi. The FACTS controller is one aspect of the power electronics revolution that is taking place in all area of electric energy. This book is the modification of the reference given and some approach has been accepted to develop the thinking process of the students in reaching a sound understanding of a broad range of topics in the FACTS controllers and application to the field of Power Systems. In general FACTS is the subject matter of this book and relatively the modification and clear understanding of the principal role to enhance controllability and power transfer capability in the ac systems. The FACTS involves conversion and/or switching power electronics in the range of a few tens to a few hundred megawatts. The book contains eight chapters. 124 pp. Englisch.…
